SAL Home GRAPHICS Processing & Visualization


This package contains some of MatLab tools for multi-scale image processing. Briefly, the tools include:

  • Recursive multi-scale image decompositions (pyramids), including Laplacian pyramids, QMFs, Wavelets, and steerable pyramids. These operate on 1D or 2D signals of arbitrary dimension. Data structures are compatible with the MatLab wavelet toolbox.
  • Fast convolution routines, with subsampling and boundary-handling.
  • Fast point-operations, histograms, histogram-matching.
  • Fast synthetic image generation: sine gratings, zone plates, fractals, etc.
  • Display routines for images and pyramids. These include several auto-scaling options, rounding to integer zoom factors to avoid resampling artifacts, and useful labeling (dimensions and gray-range).
